Variant summary

Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PM2 PM5 PP3_Strong

The NM_138295.5(PKD1L1):​c.5072G>T​(p.Cys1691Phe) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C1691S) has been classified as Likely pathogenic.

Genes affected

PKD1L1 (HGNC:18053): (polycystin 1 like 1, transient receptor potential channel interacting) This gene encodes a member of the polycystin protein family containing 11 transmembrane domains, a receptor for egg jelly (REJ) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. The encoded protein may play a role in the male reproductive system. Alternative splice variants have been described but their biological nature has not been determined.
